ABSTRACT
Worldwide, carcinoma of the oesophagus is the sixth leading reason for deaths due to malignancy. MicroRNAs (MiRs) are a cluster of small non-coding RNAs that have potent stability in stored RNA samples. This strengthens their potential as biomarkers. This study aimed to isolate MiR 21 from serum samples of carcinoma oesophagus patients and healthy subjects for determining its strength of association in various stages of the carcinoma oesophagus. This is a case-control study with 1:1 matched cases and controls. We included 40 patients of carcinoma oesophagus and 40 healthy individuals. Serum separated from venous blood samples of cases and controls was stored at - 80 °C. Total RNA was extracted, and the real-time polymerase chain reaction was used to measure the serum MiR 21. On statistical comparison, we found a marked increase in MiR 21 in cases of carcinoma oesophagus when compared with the controls (p < 0.0001). This study also showed a steady rise in the MiR 21 levels with the disease severity (p < 0.0001). Based on the result of this study, we conclude that MiR 21 levels can be used as a novel marker for assessing disease severity in carcinoma oesophagus.
ABSTRACT
Hydatid cyst is a zoonotic infection and a significant public health problem in low- and middle-income countries. A 79-year-old female patient was presented to the gynecology outpatient department with complaints of pain in the abdomen and difficulty in micturition, with a mass palpable per speculum. The ultrasound was suggestive of an ovarian cystadenocarcinoma, whereas computed tomography of the abdomen favored hydatid cyst with adnexal neoplasm as a differential diagnosis. Considering the contradictory findings, a frozen section was sent to confirm the diagnosis, which showed hooklets of Echinococcus granulosus /hydatid cyst under the microscope. This was a rare case of pelvic hydatid cyst mimicking ovarian malignancy and was associated with a less-preferred mode of investigation (frozen section). This article focuses on how a frozen section, despite its limitations and being expensive, can still be considered for accurate patient management.
ABSTRACT
Giant cells in soft tissue (ST) tumors are rare, pose great challenges to treating clinicians, and diagnosing pathologists. Common lesion with giant cells includes benign conditions such as nodular fasciitis to highly malignant lesions such as giant cell variant of malignant fibrous histiocytoma and extraskeletal osteosarcoma. Giant cell tumors of ST, extension of bony lesion to the ST are also rare possibilities. Recently, giant cell fibroblastoma and dermatofibrosarcoma protuberans have also been added to this list. These tumors show unpredictable behavior; some patients are cured by simple surgical excision whereas others develop metastasis. Diagnosing these in cytology is still more challenging. We report here a rare case of a giant cell-rich dermatofibrosarcoma protuberans in a 23-year-old male who presented with ST lesion in left forearm since 6 months. The lesion was predicted in fine-needle aspiration cytology and confirmed later with histopathology. When evaluated along with clinical features, the cytological features are very useful to distinguish between these tumors with giant cell morphology.

Malignant proliferating trichilemmal tumour (MPTT) is a rare cutaneous tumour predominantly affecting the scalp, eyelids, neck and face of elderly women. It is a large, solitary, multilobulated lesion that may arise within a pilar cyst. These tumours are largely benign, often cystic and are characterized by trichilemmal keratinisation. However at times, the tumour has an aggressive clinical course and a propensity for distant metastasis. We report a case of a 29-year-old male who presented with a scalp swelling. Histology revealed malignant proliferating trichilemmal tumour of scalp. CT thorax showed multiple nodules in both lungs suggestive of lung metastasis. The patient underwent palliative radiotherapy and chemotherapy and expired 2 months after palliation. To the best of our knowledge, malignant proliferating trichilemmal tumour of the scalp with intra-cranial extension and lung metastasis is a rare condition, and only a handful of cases are reported till date. We report a case of malignant proliferating trichilemmal tumour of the scalp with intra-cranial extension and lung metastasis with relevant discussion at the same time.
ABSTRACT
A spontaneous, intramural, intestinal haematoma is a rare complication of the anticoagulant therapy. We are reporting here, a rare case of a 63-years-old male, who presented with intestinal obstruction which was caused by an intramural and a submucosal colonic haematoma, which had resulted from warfarin administration. This patient rapidly improved after taking conservative treatment. A history of anticoagulant use with a prolonged INR value in patients who present with abdominal pain, should alert the physicians or surgeons to search for this entity. It is extremely important to recognize this syndrome at its early stages, to avoid an unnecessary operation, since the outcome is usually excellent after a conservative treatment.
